We are an international non-profit support group for all countries where there is even just one person with Prader-Willi syndrome!

As an international umbrella organisation we bring together the national Prader-Willi associations, and for countries where there are no formal associations, we support medical and parent delegates as part of our global community. IPWSO has contacts in over 100 countries, and is a world-wide parent-led support organisation. One of our key projects is to offer free diagnosis for PWS in countries where this is not available.

Creating a

Global PWS

Community

We hold a three-yearly International PWS Conference, hosted by different nations; the 10th International PWS Organisation was held in Havana, Cuba from 13-17 November 2019. We recognise that every PWS association is at a different stage of maturity and represents a distinctive cultural approach. This unity and diversity of our membership is the beauty of IPWSO, for when our unique experiences blend together they generate a much richer force than any member alone can possess.
